Acute Stanford type A aortic dissection has the characteristics of acute onset, severe condition and high mortality. Once making a definite diagnosis, surgical treatment is needed as soon as possible. It is difficult for cardiac surgeons to treat the acute aortic dissection involving the aortic sinus, which is an important risk factor for death. Improving the surgical treatment for the aortic sinus can be a key to improving the prognosis. In this review, we will introduce the modified sandwich technique for acute Stanford type A aortic dissection and the prognosis, and summarize the experiences of different modified sandwich techniques. However, there is still no unified standardized technique in aortic root repair, and there is a lack of large studies with long-term follow-up, so it is necessary to further improve the aortic root repair techniques.
